Subject AIS 700. ( new april 2018 ) with AC antenna of 2,8 m high above the boat
My AIS 700 has always worked perfectly, now suddenly I can only receive stations at a distance of +/- 1 nm where it used to be up to +/- 15 nm. The transmission of my position appears to work well and the VHF connected to the same antenna also works well, when I connect the AIS 700 to my PC via ProAIS2 the antenna appears to be OK, but I see that there are only about twenty signals inside come from stations up to +/- 1 nm, where it used to be much more stations up to +/- 15 nm
What can be the problem
